GAS HOLDER AND MIXER.

SPEGIFIQATIQN forming part of Letters Patent No. 339,900, dated April 13, 1886. Application filed Sopicniberflfl, 1885. Serial No. 177.788, (No model.)

T 0 aZZ whom, it may concern:

Be it known that we, CLARENCE M. KEMP and CHARLES E. KEMP, of the city of Baltimore, and State of Maryland, have invented certain Improvements in Gas Holders and Mixers, of which the following is a specification.

This invention relates to certain improvements in a gas holder and mixer which is employed in connection with aircarbureting apparatus, whereby the gas, or, more properly speaking, the carbnreted air in its passage into the said holder and mixer, is combined with air brought to a uniform density.

In the drawings, forming a part hereof, Figure I is a vertical section of the improved gas holder and mixer. Fig. II is a plan of Fig. I without the movable section thereof. Fig. III is a vertical section taken on a line at a right angle with thcsection-line,Fig. I. Figs. IV to XI, inclusive, are details of the invention on an enlarged scale.

A is the gas-holder formed, principally, of the stationary and movable sections, respectively represented by a and b, as is common in apparatus of this class. The inner or movable section, b, is guided in its vertical motion by means of a central stem, 0, projecting from a spider, d, secured to the bottom of the holder, and a sleeve, 6, attached to a similar spider, f, fastened to the inner surface of the head of the said movable section.

The holder is supplied with water to a height indicated by the dotted linea- 00, Figs. I and III.

B and G are respectively the gas and the air admission pipe, the former leading from the air-carbureting apparatus (which is not shown) and the latter terminating at the bottom of the holder, where it receives atmospheric air from the air-forcing device. (Not shown.) These pipes extend to a point slightly above the water line :0 m, and are covered by a tilting hood, D, pivoted to a frame,E,which is slid over the pipes and held in position by means of set-screws g and h. The hood D consists of a vessel, preferably with a curved top, '6, and flat ends or heads j, having stiffeningstrips 7;,from which the gudgeons Z and mproject.

Fig. VI is an enlarged exterior view of the hood D and the pipes B and (3; and Fig. VII

is a rear view of Fig. VI, also showing the pipes B and G.

The gudgeons Z and at rest and turn loosely in sleeves Z and m, confined by means of setscrews in bearing-boxes n, o, and p on the frame E. This frame is shown enlarged in Figs. VIII, X, and XI.

It will be understood that the hood D, supported on the frame E, as described, is susceptible of a tilting motion, and the means whereby the tilting motion is accomplished, consist as follows: The sleeve c, at a point near to its lower end,is provided with a bracket,q, (see particularly Fig.IV,) in which three views of the bracket are shown. A lever, F, two views of which are given in Fig. V, is placed loosely on the longer sleeve on and between the bearing-boxes 0 and 1); This lever has two notches,which produce the faces rand s. The outer end of the leverF passes through the bracket g, which has a hole, t, for the purpose.

G is asecond lever,als0 on the longer sleeve, on, and situated between the lever F and the bearing-box 0. On this lever, which is provided with a weight, H, are two pins, a and n, on opposite sides of the hub thereof, and the pin it is so situated as to engage alternately with similar pins,w and y,on the outer surface of the stiffening-strip 011 one end or head of the hood I) in the vibration of the said lever, as hereinafter fully described.

The pin 12 is brought alternately in contact with the faces 1' and s of the lever F as that lever is vibrated by the action of the sleeve 6 of the section b of the holder A in its vertical movement. The movement of the lever G is limited by the projections on the frame E. (See particularly Fig. VIII.)

Parts of the invention not yet alluded to will be described and their uses fully set out in the description of the operation of the invention which follows.

Supposing that gas and air are being supplied to the pipes B and (J at regular pressures, and that the movable section of the holder and the hood are in the positions shown in Figs. I and III, the gas and air flow to the holder in volumes proportionate to the relative areas of the said pipes, the means of exit for the hood being holes I in the heads 9', which are then above the water-line. As the movable section B ascends, owing to the inflation of the holder, the outer end of the lever F is carried up with the sleeve 6, and as the face 0" of the said lever comes in contact with the pin 1; on the weighted lever G that lever is carried toward a vertical position. After the lever G has passed the vertical position it falls suddenly, and its pin u strikes the pin 3 on the head of the hood. The hood is tripped and falls to the position shown by its dotted delineation in Fig. III. All communication between the pipes B and O with the interior of the holder is now out off, and the movable section b of the holder falls slowly as the gas is discharged through the pipe K to the service-pipe leading to the burners. When the section b has fallen to near its position shown in Figs.I and III, the hood is tilted in a reverse direction and carried back to its original position, when the filling operation is repeated. The proper water-line is established in filling by, means of the overflow-pipe J.

As the hood D falls in the direction of the arrow, Fig. VI, concussion of the levers and their attachments is prevented by a body of air which is sealed in the pocket L on the hood as the edge of the said pocket passes below the water-line; but thiscompressed air is gradually discharged through a hole, M, in the upper part of the pocket and thelevers allowed to fall to the lowest point.

In order that the gas and air may not commingle in the hood when the flow of the same to the holder is cut off, I provide the hood with a partition, N, (shown by dotted lines in Fig. VI and in full lines in Fig. VII,) the edge of which when the hood is'closed enters the water. By this means the gas and air are confined separately in the hood until the same is again opened.

From the foregoing it will be understood that with this invention a uniform quality as well as a uniform pressure of gas is maina39,9oo

tity of air admitted to the air-pipe C is regulated by a suitable cock provided with indieating devices, which is not shown.

It is evident that this invention canbe used simply as a gas-governor to regulate the pressure by merely dispensing with the air-admission pipe.

We claim as our invention- 1. In a gas holder and mixer, a gas and an air pipe terminating in the said holder, combined with a water-sealing hood or valve, substantially as specified.

2. In a gas holder and mixer, a gas and an air pipe terminating in the said holder, combined with a discharging tilting hood situated over the said pipes, and means to operate the said hood from the movable section of the said holder, substantially as specified.

3. In a gas holder and mixer, a gas and an air pipe terminating within the holder, a tilt ing hood situated over thesaid pipes,aweighted l l i s l lever to tilt the hood, and a lever to actuate the weighted lever connected to some part of the movable section of the said holder, all combined substantially as specified.

4. In a gas holder and mixer, a gas and an air pipe terminating in the said holder, combined with a discharging tilting hood situated over the said pipes having a separating-partition, as described, and means to operate the said hood from the movable section of the said holders, substantially as specified.

5. In combination with the tilting hood D, the air-pocket L, attached to the said hood, substantially as specified.
